Abstract: 1498157 Hydraulic tensioning device SOC D'ESTAMPAGE ET DE FORGE ARDENNES CHAMPAGNE 22 Dec 1975 [20 Dec 1974] 52399/75 Heading F1D An hydraulic tensioning device comprises a casing 2 (Fig. 3) an hydraulic pump having a piston 6 and an operating lever (4) Fig. 2 (not shown), a shaft 3 connected to piston-rod 8 which slidably engages a connecting block 9 and is connected to the piston 8 of a jack I, the shaft 3 having longitudinally extending notches defining intermediate portions having substantially transversely extending grooves which may be in the form of screw threads, and a locking means comprising a locking ring 11 having grooves and notches corresponding to those on the shaft 3 and connected by a rod 13, which extends through a slot f<SP>1</SP> in a sleeve f, to a ring 12 which may be rotated to cause the grooves of the locking ring 11  to either mesh with the grooves on the shaft 3 to thereby lock the shaft or to disengage the grooves on the shaft 3 to allow the shaft to move axially. A spring 16 may be incorporated, one end of the spring being connected to a ring 17 and the other end to the locking ring 11 so that the spring exerts a torque on the ring 11 to urge it into an unlocking position. In use, the hydraulic pump is actuated to force fluid into a chamber 7 via passages A and 8<SP>4</SP> whereby the fluid acts on the piston 8 to retract the shaft 3 and thus apply tension to a cable or rope attached to the outer end of shaft 3, the tensioning device being anchored at 1<SP>1</SP>. The ring 12 is then rotated to lock the shaft 3 against axial movement and a tap 18 is actuated so that pressure in chamber 7 is relieved via a passage B. The locking ring 11 is brought into abutment with an end plug 14 due to the tractive force exerted by the cable or rope. To release the tension fluid is pumped into the chamber 7 thereby moving the locking ring 11 a small distance away from the plug 14 and allowing the ring 11 to turn to an unlocking position under the action of the spring 16. The piston may be raised and hence the shaft 3 extended by fluid forced through the passage B. The device may be used to tension sails on sailing vessels, Fig. 1 (not shown).
